Bands of very heavy lake-effect snow will continue much of this week and could break a 24-hour United States snowfall record Tuesday night.
The coldest air of the season so far pouring across the Great Lakes will continue to trigger the lake-effect.

The snow will be blinding in some areas, falling at the rate of 3-5 inches per hour, and can be accompanied by gusty winds, thunder and lightning.
Travel will be impossible for a time in the heaviest bands of snow.
